, uses, it is especially designed and intended ioruse in connection with pneumatic ma-lting. In this method of melting the air to'be used is moistened and cooled by passing it through sprays of water.

The objectv of the invention is the production of an improved device of the character mentioned which shall be self-cleanin not liable to any considerable wear, and 0? high Mlieienev in use.

.111 the accompanying drawings, Figure 1' is a central section tirough a sprayingmozzle embodying the features-of any invention. Figs. .3 and 3 are sectional views taken through said nozzle on dotted lines 2 2 and 3 2%, respectively, of Fig. 1.

The embodiment of this invention shown in the drawings comprises a substantially e \lindrieal body portion 1, having a chamber 1 therein. Upon its inner walls at. one end said body portion is serew-threaded to receive a peripherally-serew-t hreaded elosingalislt 3, said disk having an oetagonal annular -lfor engagement b a wronelf' h'aid disk also has a tubular exteriorly-serew-threadml integral stein :"i, by means of whieh the nozzle ma be mounted upon a. \rater-supptv pipe.

By reason of the curved form of the vanes 10, 11, and 12 said streams aregiven a gyrat-ory'motion' and issue'trom the orifice b as a thin whirling sheet. or spray. The vanes 10, 11, and 12 form between them an inner chamber communicating with the .the ad'aeent ends of said vanes. v I

litv will be noted that t-he deviee comprises but few parts, is easily assembled and taken apart, and that. it has no movable members, and thus is not subject to appreciable wear nor liable to breakage.

I claim as my invention- 1. A spra vi1'1g-nozzle comprising a ehanrbeged body portion having an inlet and a discharge oril'iee; and a disk removably supported within said ehamlwred body portion, said disk permitting the passage of liquid around its edges and being provided with a '2 A spra \'mgnozzle eoi'nprisii'ig a chambered luid portionprovided with an ml t. andan outlet-.n meml'i'er extending nor "the ehamher in said bod) portion and lying between the inlet and the outlet and adapted to permit the passage of the-liquid around its edges. and a plurality of curved vanes on said member arranged t o 'n'eventthe 'pas sage of the liquid through said outlet save between the adjaeent ends of said vanes.

13. spra \'ing-nozzle eomprising a. ehambered body portion. an inlet in one wall of said liorl') portion. an outlet in the opposite wall of said bod portion. a member extending transversetv between said end w ills and adapted to permit thopassage ol' l' iid pastils edges. aml enrved \"anes extending l tween said member and the-end wall-pro \ided with the outlet. said vanes being arranged to l'orm an im-losure open to the inllowing lluid ol\l between the adjarent ends of said vanes.

i. spraying-nozzle eo'mprising a \'l'in drieal rhamlier bod portion having an inlet in one of its walls: a ventral ronieal tip in its opposite wall. said tip being provided with a.

discharge-orifice, an imperforate disk extending across the interior of said body portion, lugs located upon the periphery of said I disk, for spaci itln said body portion, and i l 5 aplurelity of enrved vanes on the side of" said disk adjacent to said disehar e-orifiee, said a i -disk and vanes preventing t e passage of i liguid' from said outlet to said discharge {Loflfice save between the adjacent ends of wfssid vane's. i

A spra ing-nozzle comprising a sub -,,sthintially cy in'drical body portionha'ving a "chamber therein, a closure-diskfor closing one'end of'said body portion, said disk having 5 a central tubular stein, a Wall closing the op- ;posiitsl end of said body portion, said well k g havlnv a central corneal tip provided with a disch. georifioe, a disk extending transverse/ll, between said tubular stem and said disehzhge-orifice, and means extending be 'tween'said disk'and theend wall having the disehargleorifice for giving the liquid passing thrcihgh said body portion a gyratory nioiisiiirayin nozzle comprising a sub ntral tubular stein, awallelosing the opii; v i

I is" eylin rical bodyportion having a 'therein;;a= ielosure-disk for closing it said body portion,said disk having 'posite end of said body 'portion,said wail havinga central conical tip provided with a discharge-orifice, a disk extending transversely between said tubular stern and said dis charge-orifice, and curved vanes on said disk L ehamher therein a closing-disk for closing i one end ofsald body-portion, Sfiddfillsli having ;a tubular cylindrical securing-stern fixed thereto, an end wall closing the opposite end of SiLld-iJOdY portion and having a central dischargeorifice, a disk lying tral'isversely between said tubular stem and said discharge-orifice, saiddisk havln r a plurality of curved vanes upon its slde an acent to said said closing-disk and sai other disk tending to force them apart.
